上传图片时Firebase存储崩溃

Question

我正在尝试将图像上传到Firebase存储，但徒劳无功。

当我添加成功上传方法或任何其他方法导致应用程序崩溃但没有它们时，应用程序上传图像就没有问题。

我确定firebase是真实的。

public class add extends Activity
{
    private Button button1;
    private ImageView im;
    private EditText edit1,edit2;

    private String im_link,im_name;
    public final int REQ_CD_PICK = 101;
    private Intent pick = new Intent(Intent.ACTION_GET_CONTENT);
    private int k;

    private HashMap<String, Object> map = new HashMap<>();
    private DatabaseReference post;
    private StorageReference up = FirebaseStorage.getInstance().getReference("up");

    private ProgressBar prog;
    private Calendar date = Calendar.getInstance();

       @Override
        protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.user);
        FirebaseApp.initializeApp(this);
        edit1=findViewById(R.id.edit1);
        edit2=findViewById(R.id.edit2);
        button1=findViewById(R.id.btn);
        pick.setType("image/*");
        pick.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
        im=findViewById(R.id.userImageView);

            post=FirebaseDatabase.getInstance().getReference().child("post");

        im.setOnClickListener(new View.OnClickListener(){
            public void onClick(View view){
                startActivityForResult(pick, REQ_CD_PICK);
            }
        });

            button1.setOnClickListener(new View.OnClickListener(){
                    public void onClick(View view){
                        if(edit1.getText().length()<15){
                            edit1.setError("ادخل العنوان");
                        }
                        else if(edit2.getText().length()<50){
                            edit2.setError("أدخل نص المقال");
                        }else{
                            if(k>0){
                            edit1.setVisibility(View.GONE);

                            up.child(im_name).putFile(Uri.fromFile(new File(im_link)))
